RITA Speaks: What Technology Can Do for Transportation Safety

Among the myriad of smaller agencies that comprise the U.S. DOT, the Research and Innovative Technology Administration (RITA) tends to stay in the background, not unlike the wonky, computer-hacking sidekicks often found in action movies.

But the RITA, which has a budget of nearly $13 million, is getting ready for its close-up with an in-depth examination of intelligent transport systems, or ITS — the umbrella term for technological improvements that can enhance safety and decrease congestion, as well as the emissions that tend to accompany thick traffic.

In a briefing this afternoon, RITA chief Peter Appel warned: "ITS is not a silver bullet. Ultimately, more responsible drivers will lead to safer roads."

But he predicted that the RITA’s work would yield safety dividends for all road users, allowing drivers, pedestrians, and cyclists to better communicate with one another to prevent crashes.

The ITS program "is only successful if it’s truly cross-modal," ready to be deployed for bike-ped use as well as by drivers, according to Appel.

For example, he said, the RITA’s vehicle-to-vehicle communication program is equally applicable to travelers using their feet. A large number of pedestrians and cyclists are likely to be emitting a wireless signal, "whether it’s the cell phone they’re carrying or
some other device," Appel explained.

Thus, an auto with vehicle-to-vehicle communication devices could also pick up the wireless footprint of any approaching traveler, alerting drivers to stop and yield to a pedestrian or keep their doors closed to avoid hitting a cyclist.

"We feel that with better warning, both to bicyclists and drivers …
there’s a lot we can do" to bring down the number of road injuries and fatalities, Appel said.

The RITA’s mission also encompasses real-time traffic and transit updates that can be delivered to individual travelers, giving them the information needed to avoid congested roads and take alternate rail routes as needed. For more information on ITS, check out the U.S. DOT’s dedicated website.

There's ample research out there backing up the safety benefits of streets with protected bikeways and slow car speeds. But what about the critically important yet less tangible factor of individual attitudes -- how does the mind of the person behind the wheel affect driver behavior toward cyclists? A new report from Portland State University looks at the question.

Despite the number of two-wheeled cop patrols around some cities, police aren’t always the most bike-minded bunch. When there’s a conflict between motorists and cyclists, they’re often inclined to take the motorist’s side. As Streetsblog has reported, police in New York City care more about drunk pedestrians than unsafe drivers, despite the fact that most fatalities are caused by […]

Delaware got rid of its “Share the Road” signs about two years ago. Though the signs were designed to affirm cyclists’ rights to the road, they were widely misinterpreted — by both motorists and cyclists — as an exhortation to cyclists to stop “hogging” the road, or as a recommendation that drivers and cyclists share a lane (leading to tight squeezes and […]

Appeals for courtesy between drivers and cyclists and pedestrians are pretty standard fare for traffic safety campaigns. In London, it’s “Share the Road.” In Utah, they have “Respect is a Two-Way Street.” Is this the best we can do? Robert Wright at the Invisible Visible Man was thinking this over after a taxi driver nearly struck […]

In too many cities, newspaper coverage of bicycling has stoked some of the darker aspects of human nature. Opinion pieces about bike lanes tend to cater to the reactionary opposition, goading the trolls of the comments section, where casual death threats are standard fare. But a newspaper in South Florida has taken a very different approach over […]
